Equal-weight USD index, rebased to 100.0 on the first trading day of 2026. It covers AI photonics, InP and GaAs substrates, HBM memory, AI cloud infrastructure, and European semiconductor candidates.
Top contributors since the base date are SIVE.ST, AXTI, AAOI, MU, RPI.L. The only constituent still below the base-date mark is IREN.
Heatmap color shows each constituent's 2026 return from the index base date. Tile area shows current drifted portfolio weight after returns, assuming no rebalance from the initial equal-weight basket.

Methodology: equal-weight at each rebalance, USD-denominated, and reviewed daily after the automated update. The page and constituents CSV show current drifted weights before rebalance. US stocks use USD closes directly. XFAB.PA, SIVE.ST, and RPI.L use historical EURUSD, SEKUSD, and GBPUSD conversion; RPI.L is converted from GBX to GBP first.
Latest curve point: 2026-08-10. Price source: Yahoo Finance chart data for stocks and FX pairs. Benchmark comparison lines extend through the latest available US close on 2026-08-10. CSV files: history, constituents, benchmarks
The basket is built around public-market AI infrastructure bottlenecks: optical connectivity, memory bandwidth, compound-semiconductor substrates, and AI cloud capacity. It is designed as a monitoring index, not as an investable benchmark.
Large moves should be checked against orders, backlog, revenue conversion, gross margin, dilution, customer concentration, and valuation. A rising index without reported revenue confirmation should be treated as expectations-driven.
